Question

For each of the following substituents, indicate whether it withdraws electrons inductively, donates electrons by hyperconjugation, withdraws electrons by resonance, or donates electrons by resonance. (Effects should be compared with that of a hydrogen: remember that many substituents can be characterized in more than one way.) Withdraws electrons inductively. Donates electrons by hyperconjugation. Withdraws electrons by resonance. Donates electrons by resonance. Withdraws electrons inductively. Donates electrons by hyperconjugation. Withdraws electrons by resonance. Donates electrons by resonance.

Explanation / Answer

NHCH3 is an example of strongly activating group,

Which will withdraws electrons inductively.

Which donates electrons bt resonance.

-OCH3: donates its electron by the resonance and withdraws electron inductively.
